Title: Improvements in or relating to metallising the surfaces of ceramic bodies
Inventor: BARNARD ROY MAYNE
IPC: C04B41/51
Filed: 1951-02-09
Abstract: In a method of forming an adherent metal surface layer on ceramic material a metal oxide applied to the ceramic surface, or obtained by oxidizing an applied sheet of metal foil or sintered in powder form together with powdered ceramic material, is heated above its melting-point to bond it firmly to the ceramic and subsequently reduced to metal.  Metal coatings of copper, silver, iron or nickel may be provided on ceramics of kaolin, talc or titanium dioxide, the use of thin copper foil which is applied to the ceramic surface, heated in air to 1100 DEG  C. to form cupric oxide which melts and bonds with the ceramic and is reduced in hydrogen above 450 DEG  C. being described.  Ceramic bushes suitable for use as electric terminal seals made by the method are described and illustrated.

[Class 99 (ii)] Relates to the laying of pipes in tunnels or headings only a few inches larger than the outside diameter of the pipe, by supporting the pipe a with a spigot c and jointing ring b at one end of the heading, Fig. 2, conveying the second pipe e through the heading by means of the carriage f, having a table g vertically adjustable by the screw k, engaging the socket d over the spigot c, inserting the strap h supported by two jacks, Fig. 4, removing the carriage, supplying concrete or other blocks to support the new pipe section and removing the strap and jacks. This process is repeated until the correct length of pipe is layed. The carriage, whose adjusting screw must be at the rear, may have three wheels when the floor of the heading is concreted, or may, if concrete is not used, have four wheels to 'run on a narrow gauge rail track. If it is required to lay the pipes from the centre of the heading a special section with two spigot ends is first layed and the aforesaid method may then be applied from both ends of the heading.

Abstract: 554,651. Machine gun mountings. BOULTON PAUL AIRCRAFT, Ltd. (Soc. d'Applications des Machines-Motrices). Feb. 7, 1939, No. 4058. [Class 92 (i)] Mountings for heavy machine guns, particularly those having means as described in Specification 494,304 for reducing the amplitude of recoil when firing continuously, are provided with a hydraulic recoil and run-out brake including two valves 84, 78, Fig. 5, both of which open automatically at the beginning of recoil to provide free recoil movement the valve 84 closing at the beginning and the other 78 at the end of run out. The valve 78 is outside the amplitude of movement for continuous fire and functions only when firing ceases or single shots are fired. The gun (not shown) is supported by members 48, 18, Fig. 2, the latter being in the form of a crank with trunnions 16 and thickened webs which carry fixed cylinders 22 for pistons 40 connected by rods 42 and pins 46 with the member 48 to which the gun is connected. Liquid under pressure is admitted to each brake through a non-return valve 64 leading to a reservoir 54 and is kept under pressure by a spring-pressed piston 56. The pistons 40 which serve to compress the return springs 34 against fixed abutments 36‹ are each made hollow to form a brake cylinder and to receive a piston valve 84 having slight play on the end of its fixed rod 68, the interior of which forms a passage for liquid from the reservoir 54. During recoil, each piston 40 moves to the left and the valves 84, 78 both open to provide free passage of liquid from right to left of the piston valve 84. During run-out, each piston 40 moves to the right and the rear end of the rod 68 forms a valve seat 82 with the piston valve 84 at the beginning of run-out ; the liquid then passing through restricted openings 76. At the end of run-out when firing ceases, the member 78 on each piston 40 forms a valve by entering a space in the rear end of the rod 68.

Title: Frequency modulation system
IPC: H03C3/14
Filed: 1947-02-14
Abstract: 628,641. Frequency modulation. STANDARD TELEPHONES & CABLES, Ltd. Feb. 14, 1947, No. 4305. Convention date, Feb. 22, 1946. [Class 40 (v)] The tuned circuit LC of a frequency-modulated oscillator To is shunted by a thermionic reactance valve Tm, the grid of which is supplied with quadrature voltage through an amplifier valve Ta. The grid of the valve Ta is fed by a coil coupled to the. circuit LC, and its anode circuit is given a capacitative impedance at the oscillation frequency by the provision of a condenser Ca, or by the inherent anode capacity, so as to provide the necessary 90 degrees phase shift. Modulation voltage Um is applied to the cathode of the amplifier Ta, and the resulting voltage across the anode resistor Ra is transferred to the control grid of the reactance valve Tm. The system thus provides amplified oscillatory voltage at the grid of the reactance valve and enables large frequency deviations to be developed. This effect is enhanced by lowering the anode oscillatory voltage on the reactance valve, by connecting across the oscillatory circuit LC a limiting diode T2 in series with a source UL biassing the cathode positively.

Abstract: 500,318. Fluid-pressure servomotorcontrol systems. EXPERIMENTAL LABORATORIES, Inc. Feb. 11, 1938, No. 4368. Convention date, Jan. 3. [Class 135] [Also in Group XIII] In a boiler generating a mixture of steam and combustion products for supply through a pipe C to a heating system, a valve 61 controlling the fuel supply to the burner B is operated by a diaphragm in a chamber 68 connected above the diaphragm by a pipe 74 to the suction side of a fan E which draws the non-condensable gases from the system. The pipe 74 opens through a branch 76 into a water seal formed by a chamber K, into which projects a pipe 78 opening into the boiler just below the normal water level. The fuel-supply valve is normally maintained opened by the fan suction, but when the boiler water-level falls and the water seal is broken, the space above the valve diaphragm is placed under boiler pressure and the valve is closed.
